By chance, I've heard about "delta-time and framerate". That's something totally new for me. 2-3 weeks ago, I posted a topic about performance and no one mentioned that.
I suppose I should have to apply it manually on all my project. But before to do so, I'd like to know :
Thanks to that, can I "force" a game to be fast on a slow computer (that makes the game run at 30fps), and will it look like if it was really running at 60fps??
It would be too nice to be true, but I might have misunderstood... What are the disadvantages? Why isn't it a default feature?
